What is the best way to detect a mobile device?

Is there an approach to identify whether a user is utilizing a mobile phone in jQuery? Something like the CSS @media attribute? I might want to run an alternate script if the browser is on a handheld device.

The jQuery $.browser function is not what I am looking for.

mobile jquery javascript

function isMobile() { return ('ontouchstart' in document.documentElement); }

However above code doesn't take into account the case for laptops with touchscreen. Thus, I provide this second version,



function isMobile() {

  try{ document.createEvent("TouchEvent"); return true; }

  catch(e){ return false; }

}

A simple and effective one-liner:

function isMobile() { return ('ontouchstart' in document.documentElement); }

However, above code doesn't take into account the case for laptops with touchscreen.

function isMobile() {

  try{ document.createEvent("TouchEvent"); return true; }

  catch(e){ return false; }

}
